The Polymer80 P80-JIG-RL556v3 Jig Kit comes complete with essential parts as described: Polymer80 P80-JIG-RL556v3 Jig Kit If you are building an AR-15 from an 80% lower, the polymer80 p80-jig-rl556v3 jig kit is the tool that turns a block of polymer into a functional receiver. This is the third-generation jig from Polymer80, designed specifically for their RL556v3 frame. It is not a complete build kit, but the essential guide and cutting block that ensures your drilling and routing stay on spec. We have sold a lot of these, and we hear from customers that this jig simplifies a process that can otherwise feel intimidating. Let us walk through exactly what you are getting. Overview The polymer80 p80-jig-rl556v3 jig kit replaces the older gen 2 design with improvements in alignment and material rigidity. It works exclusively with the Polymer80 RL556v3 80% lower receiver. The kit includes the jig body, drill bits, end mill, and all necessary hardware to complete the pocket and pin holes. No additional specialty tools are required beyond a hand drill and a few common shop items. This is the current production version, so it reflects the latest tolerances and design tweaks from Polymer80. Features & Specs This jig is built around repeatability. The RL556v3 lower drops into the jig and locks in place with a tensioning system that prevents shifting during work. The hardened steel drill bushings guide your bits for the trigger pin and hammer pin holes, taking the guesswork out of alignment. The routing block has raised rails that match the fire control pocket profile, so you remove material evenly without over-cutting. Hardened steel drill bushings for trigger and hammer pin holes, sized for standard AR-15 pins Reinforced polymer jig body with metal lock bars to prevent flex during milling Includes two carbide-tipped end mills, two drill bits, and all mounting screws and wrenches Specs are straightforward: manufactured by Polymer80, category is build kits, and the kit is intended for single-use on one RL556v3 lower. The jig body itself is reusable if you plan multiple builds, but the included cutting tools are consumable. The end mills are 1/8 inch shank, compatible with most standard hand drills or a drill press. Who It's For This jig kit is for the home builder who wants to complete an 80% lower without sending it to a machine shop. If you have basic mechanical aptitude and can follow a step-by-step process, this kit is very approachable. It is also for the builder who already owns an RL556v3 lower and needs the correct jig to finish it. The polymer80 p80-jig-rl556v3 jig kit is not for someone looking for a complete firearm or a pre-assembled receiver. It is a tool, and it assumes you are comfortable with drilling and filing. We see first-time builders use this successfully, but patience and attention to detail matter more than experience. Home builders completing their first or tenth AR-15 lower Shooters who want to legally manufacture their own firearm for personal use Anyone who already owns a Polymer80 RL556v3 lower and needs the matching jig If you have already drilled an 80% lower before, the improvements in this v3 jig will be noticeable. The locking mechanism holds the lower more securely, and the bushing alignment is tighter than previous generations. Shipping & FFL This jig kit ships directly to your door.
